FRANK M. POWERS, or CHICAGO, ILLINOIS, 'ASSIGNOR r rowERs & COMPANY. OF I CHICAGO, ILLINOIS, A CORPORATION or ILLINOIS I TENT WINDOW Application. filed A ril 18,

This invention relates to improvements in tent windows and more especially such windows that can be opened and closed by the raising or lowering of a flap.

In window construction of the character referred to, it has been customary to provide a flap, usually on the outside of the wall, with means for raising or lowering the same to open or close the window. In this kind of construction, difficulty has been encountered in retaining the flap in its various positions.

Among the features of my invention is the provision of means for housing or retaining the flap so that it is guarded against injury and prevented from being blown out of its proper position or away rom the wall. At the same time, the operation of the flap is not interfered with; and its effectiveness is greatly increased.

Other features and advantages of my invention will appear more fully as I proceed with my specification.

In that form of device embodying the features of my invention shown in the accompanying drawing, Fig. 1 is a view in side elevation from the outside with a portion broken away; Fig. 2 is a similar view from the inside; Fig. 3 is a view taken as indicated by f, the line 3 of Fig. 1; Fig. 4 is a view taken as indicated at line 4 of Fig. 1; and Fig. 5 is a view similar to Fig. 3 showing the flap raised.

As shown in the drawing, 10 may indicate a tent wall with an opening 11 therein covered M by a sheet of netting or similar material 12, for example marquisette.

13 indicates a flap with its upper edges 14 sewed or otherwise attached to the outside of the wall 10 above the opening 11. This flap is large enough so that when lowered it will cover the opening. Means are provided for raising and lowering this flap. As here shown, such means includes a rope or cord 15 on each side. One end of the cord 15 1s attached at 15 to the lower corner of the flap. From this point, the cord extends downwardly through an eye 16 in the tent wall thence upwardly on the inside of the wall, as 1nd1- cated by 15 some distance above the upper K edge 14 of the flap and thence outwardly through the eye 17 and thence downwardly 1 32. seriai N t @5359.

where its other end is attachedat 15 to the fla'p'about halfway between the upper and lower edges thereof. It will be seen that if the portion of the cord 15 on each side, on the lnside of the wall, is pulled upwardly, itwill cause the ends of the cords 15 to pull the. lower corners of the flap down until the? window is covered. Reverse movement of the cords will pull upon the ends attached at 15 at both sides of the fiapuntil the same is pulled up as shown inFig. 5 and the window completely uncovered or opened. i l 7 On the outside of the wallthere is at-' tached a cover sheet completely covering the flap by permittingthe raising and lowering thereof as above described. This cover sheet is provided with an opening registering with the opening in-the wall and said opening in the cover sheet maylikewise, if desired, be 1 covered withsuitablenetting, and reinforcmg strips if necessary or desirable. As here shown, this cover sheet includes vertical str ps 18 on each side with an upper cross strip 18 and a lower cross strip 18 This leaves an opening 19 in the cover sheet which registers with the opening 11 in the Wall 10. As here shown, this opening is slightly larger than the opening 11. As here shown, also, the opening 19 is covered with a sheet of net- I ting 20, for example marquisette, and in order to strengthen and reinforce the same I have provided two centrally arranged intersecting straps of canvas or other suitable material 21. It will be seen that theportion 18 of the cover sheet is wide enough to permit the flap 8 13 to be completely raised thereunder as shown in Fig. 5. The cover sheet, including the straps 18 and cross pieces 18 and 18 is wide enough to entirely cover the .flap which, it will be noted, must be somewhat wider than the smallerof the two openings 11 and 19. As here shown, the flap is somewhat wider than the openings 19.

The foregoing detailed description has been 7 given for clearness of understanding only, and no unnecessary limitations should be understood therefrom, but the appended claims should be construed as broadly as permissible, in view of the prior art.

What I regard as new, and desire to secure by Letters Patent, is:

1. In combination with a tent wall having an opening therein; a flap with its upper edge attached to the outside of the wall above the opening,rsaid flap adapted to be lowered to cover the opening or raised to uncover" the same; means for raising and lowering said flap; and a cover sheet of material attached to the outside ofthe wall completely'covering said flap when said flap is raised, said coven sheet being provided with an opening registering with the opening in the wall.

2. A device as claimed in claim 1 in which i the opening in the cover sheet is covered with a sheet of netting. 7

A device as claimed in claim 1 in which the opening in the cover sheet is covered with a sheet of netting and a strip of reinforcing material.

4. A device as claimed in claim 1, in which the means for raising and lowering the flap includes a rope on each side with one end at tached to a lower corner said rope extending through the wall thence upwardly inside of the wall to a point substantially above the upper edge of the flap thence outwardly through the wall and thence downwardly with its other end attached to the flap substantially midway between the upper and lower edges thereof.

5 A device as claimed in claim 1 in which the opening in the tent wall is covered by a sheet of netting; V
